Burr pressing roller with super wear-resistant nano coating

Abstract

The invention discloses a burr pressing roller with a super wear-resistant nano coating. The burr pressing roller comprises an outer roller body, an inner roller body and a rotary shaft, wherein the inner roller body is hollow; the inner roller body is arranged on the inner peripheral wall of the outer roller body; the rotary shaft is inserted into the inner roller body; and the wear-resistant nano coating is arranged on the surface of the outer roller body. The burr pressing roller is provided with a nano coating composite material with reduced wear resistance and rough resistance, and the composite material has good physical properties and chemical properties, so that combining capacity between the coating and a base material can be improved; meanwhile, reduction ability of wear resistance and rough resistance of the surface of the burr pressing roller is improved, mechanical load and high temperature resistance are integrated, and the usage period is prolonged to be 6-8 months or more from original two months, and is greater longer than that of a cold-rolled burr pressing roller in the prior art, so that unit operation efficiency and product quality are effectively improved, spare part consumption is reduced, and reliable guarantee is provided for cost decreasing and benefit increasing of a client.

Description

technical field [0001] The invention relates to the technical field of iron and steel industry equipment, in particular to a deburring licker-in roller with a super wear-resistant nano-coating. Background technique [0002] During the high-speed operation of the current deburring licker-in rollers (also known as steel rollers), there will be insufficient smooth rotation, low vibration critical point, and large vibrations. It is difficult for the deburring licker-in rollers (also known as steel rollers) to achieve high-speed operation, and In the actual production process, due to the stress generated by the uneven temperature field in the working environment of the licker-in roller (also known as the steel roller), as the roller rotates, the temperature field changes periodically, and the stress also changes accordingly, and the temperature of the roller surface is higher. High, the fatigue strength decreases, which causes cracks on the surface of the roller due to fatigue. A...

[0002] During the high-speed operation of the current deburring licker-in rollers (also known as steel rollers), there will be insufficient smooth rotation, low vibration critical points, and large vibrations. It is difficult for the deburring licker-in rollers (also known as steel rollers) to achieve high-speed operation, and In the actual production process, due to the stress generated by the uneven temperature field in the working environment of the licker-in roller (also known as the steel roller), as the roller rotates, the temperature field changes periodically, and the stress also changes accordingly, and the temperature of the roller surface is higher. High, the fatigue strength decreases, which causes cracks on the surface of the roller due to fatigue. At the same time, the deburring roller (also known as the steel roller) is subjected to mechanical stress while the strip is pickling, and the roller surface is severely worn. It not only affects the quality of the strip, but also seriously affects the service life of the deburring roller (also known as the steel roller). The service life of the roller in the original state is 2 months

The current solution is: surfacing wear-resistant materials on the roll surface to improve the wear resistance of the roll surface, or spraying wear-resistant layers with micron materials to improve the service life of the rolls. Neither method can solve the wear of the roll surface very well. , cracks, and the drop in roughness lead to problems such as strip slippage, and the welding layer and sprayed micron coating are easy to peel off
